## Formula

P = ( r * A ) / ( 1 – (1+r)^{-N})

**P** = Payment Amount
**A** = Loan Amount
**r** = Rate of Interest (compounded)
**N** = Number of Payments

**Rate of Interest Compounded is,**

- Monthly,
**r = i / 1200 и N = n * 12**
- Quarterly,
**r = i / 400 и N = n * 4**
- Half yearly,
**r = i / 200 и N = n * 2**
- Yearly,
**r = i / 100 и N = n**
